FLIER FOR SPINNING-MACHINES.

SPECIFICATION formingpart of Letters Patent No. 236,942, dated January 25, 1881. Application led August 28, 1880. (No model.)

To all whom it may concern Be it known that I, JOHN F. FOSS, of the city of Lowell, county of Middlesex, and State of Massachusetts, have invented a new and useful Improvement in Fliers for Spinning- Machines, of which the following is a specification.

My invention relates to machines in which a roping or coarse roving is twisted sufficiently to be spun upon rin gor other form of spinningmachines which linish the thread.

The object of my invention is to provide a Hier with a spindle which shall at al1`times be supported at its ends, which shall be extremely rigid, shall be of the least possible length, and at the Sametime admit of the conr venient and easy removal or replacement of the bobbins. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is an elevation of the entire iiier and spindle. Fig. 2 is an enlarged broken view, partly in section and partly in elevation.

A is the iier, consisting of the ends e and e and sides f. To the top end, e, is attached the usual upward-projecting hollow stud, j, which forms the upper bearing of the flier, and through which the roping is carried into the ilier-spindle. Directly below the stud, on the axial line of the flier, is extended the hollow nose D. Attached to this nose is a springcatch, d, having an end, d2, projecting through the shell of the nose,and extending a short distance into the cylindrical opening of its interior. Attached to the bottom e is the sleeve a, which forms the lower bearing of the iiier. Attached to this sleeve is the pinion s, which is driven by the usual bevel-gear wheel of such machines.

B is the spindle, driven by the spline bevelpinion b4. The spindle B is made hollow and provided with a button, b, at its top, having an upward-extending pin, b2, which catches into a notch in the bottom of the bobbin and carries it Withthe spindle.

O is af guide-rod, extending, when in operative position, from within the hollow of the spindle B, on the line ot' the bottom e of the flier, up through the bobbin E, into the hollow nose D, where it is caught and held by the projecting end d2 of the snap-catch d, which projects into the annular groove cut near the top of and around the rod G.

rlhe rod C, being of substantially the same diameter as the opening through the bobbin, and extending from the bottom to the top of the hier, and closely fitting the bearings in which it is sustained at its top and bottom, sustains the bobbin while in all parts ot' its traverse, and prevents its vibration or gyration, while the spindle, being somewhat larger and tubular, possesses a rigidity not to be obtained in a small Solid spindle.

The spindle B, being lifted by the traverserail upon which its step is plaoed,rises through the sleeve a and upon the rod C, carrying upward the bobbin E as the roving is wound upon it, and thus lays successive layers upon it as it rises and falls within the iiier, in the usual and well-known manner, while the spindle, being extended within the filer only to the lower part of the bobbin, has less length and less tendency to vibrate or gyrate, and, being sustained by the rod C as well as by the sleeve a and its step-bearing b5, it has at all times three points of support-one at each end and one in -the middle-thus Sustaining it far better than any spindle can be which, by the rise of the traverse-rail, is projected up into the ier away from its points of support.

When it is desired to doit or remove the bobbin from the flier, when full, to substitute an empty one, it is done by retracting the projecting end d2 of the spring-catch d, by pressing upon the upper end of the catch, when the rod C, being free, drops down into the hollow spindle a little farther than the length of the bobbin, when the bobbin can be lifted up and removed, and an empty one substituted, after which the operator, by seizing the top of the rod C, lifts it, and as it is accurately directed by its t in the hollow spindle, it enters the hollow nose D without dificulty, and is caught by the catch d and held in position. As the catch d engages into an annular groove in the rod C, it does not prevent the rotation of the rod if the frictional contact of the spindle and bobbin be sufficient therefor, while the rod being cylindrical, as is also the opening into which it enters in the Spindle, it is free to ro- 10o and guide-rod C with the flier A, provided with a connecting mechanism which will sustain and hold the top of the guide-rod, substanz5 tially as described. v

3. The combination of the flier A, provided with the hollow nose D and. the catch d, with the guide-rod C, which is provided with an annular groove, c, substantially as described. zo
